Werra-HEATER' To all whom@ may concern: f

Be it knovvny that 1W1KLLIAM Sriiivoiin7 a citizen of the United gStates, iesidingat Philadelphia, in thefcounty; ofIhiladelphiar` and Statefof Pennsylvania, havevin vented certain Anevvand useful'` Improve-` ments in fWater-He'aters, of which the following is aispeciiication. This invention `relatesto the; subject hof water heaters ,of ythe1s0calledy instantaneous type, and has yparticular reference to a novel device ofithis character constructed especially for rapidly heating running Waten to ahi'gh temperature. p

he primaryobject of the, invention'is to provide a practical devicev ofgthe character indicated that'vvill freely exposethe Waterk to a maximum heating surface to insure the instantaneous heating thereof by means of a gasor `oil llame. Many devices ofv this character employ \a.l,heating-coil]i7 but this method does not present,as a rule7 anade-y quatel heating surface tothe flame, becausey the bottom coil only receives the; directlieat of the flame.v Accordingly, the present in-l vention` contemplates passingthe Water in .1- a zigzag course through a plurality ofwaten tubes of.y comparatively. small diameter which are indirect contact With the flame, and thenf passing it through an incasing Water-jacket tof extended. area and restricted thickness,l and which jacket is so ycom-y` bined With the Water tubes astojform a housing-hood therefor..

Another object of the invention is-to pro-y vide a novel, simple and substantial construction vvliich may `beveasily and economi-y cally manufactured,` and whichr` willbe not only of special utility in household heating systems, butat the same time maybe used to advantage for thegeneration ofsteam.,

'l lith the aboveandother objects in vievv-y which Will more-readily appear as thenature of the invention is betterunderstood the same consists in the novel construction,

. combination and arrangement of partsvhereinafter more fully described,fillustrated and claimed. i

A preferred and practical embodiment of theinvention is illustrated the'v accom` panying drawings in 'Which-e Figure l is a'transversesectional vievv'of one form of the invention arranged Within a suitable casing. Fig. 2 is a bottom plane View of the heating unit Without the casing.y

rfor the sake natenteaaugi io, ieiaj `'cal sectional View of a modilicationof theinvention.l n'

Similary referencev characters designate corresponding parts ythroughout the severalf Fig. 3 is a vert figures `of the drawings.

, `Referring the numeral l designates a suitable casing havingA supported therein upon theubloc'ks 2.` or other suitable supportingV means, a

heating unit designated in its.,-e':ntirety by the numeral 3. Directly beneath the saidheating yunit 3 there is supported a suitable burner L which inthe presentin-stance is shoivnto be apgas-fburner, thoughitvvill of course ybe lunderstood that any, other desired v to thek details' of a `construction' shown in the several figures ofthe drawings,

type ofburner may be usedwith equal fafy H cility.

Eigs, l and 2 essentiallycomprises 'oppor sitely arranged Waterfheaders and 6 which i offconveniencezmay berespecf-l tively termedpa receiving header and ytransf ferring header. These l headers are,y con-y nected by a plurality of ivatertubes 7"vvl1ich are* preferably of comparatively small diameter and exposed to direct contact With I The forni of the inventiongdisclosed. ins

the iamefrom the burner 4. The receiving yheader 5 is provided at one end VWitha Water inlet connection 8, `While the opposite or transferring header 6 is in communicationl through a suitable port 9 ywith a flat Water-k ]acket lO of` restricted bore andextended` area. That isto say, thewater jacket l0 is preferably very thin, and arrangeddirectly above they bank, of Water tubes? forming a housing-hood thereforso vthat heat isvdirected thereagainst at the same time that'itis directed against the tubes 7. Thisjacket is co-extensive With the Width andjlength of the bank ofWater tubes and headers;A and atA its end opposite the location of the port 9 is provided With` a taperedl or convergent;

outletlportion ll havinglat itsapeir` an outlet nipple yl2, tolead the `Water-v.y to the dise tributing piping. i i

yFrom ,th

n y foregoingdescription one type offtheinvention, .it will bek apparent that Water entering the tubes 7 which are highly heated bythe fiame from the burner 4 into the header 6 from whence it is transferred to the Water jacket 10 and retraces its course back over the flame toward the receiving header 5v a through theinlet connection 8Will beforcedf kthrough the bank of convergent outlet portion 11 Vfrom which it v 1 makes its ,exit through to a faucet'or some portion of the plumbing the outlet nipple 12 system. l f Y Themodiiication of the invention Yshown in Fig. 3 'providesamore extensive heating l surface for the Water thandoesthe other typeof the invention. This form,`like the other, essentially comprises oppositely arranged Water headers 13 and 14, the former beingthe receiving header and the latter the transferring header.

lVith particular refheader '13, it Twill be erenc'e` to the receiving observed that the same is providedl vvithia .into a receiving compartment 16 and central partition V15 Which'divides the same Z livery compartment 17, the former communicating with the `water supply by means ofafpipe' connection 18'. The 'compartment 16 which extends the entire length 'ofthe' header,"'a'nd receives Water from the source of supply communicates. With the transfer-V ring header `14: by means of` a plurality of arched v'vater tubes 19,-thus conducting the cold Water directly over thefiame-'froin a burner @Hand discharging the same into the chamber 20 of the header 14:: For the purposerof retarding passage ofthe Waterfso that it'will get`r the full benefit ofthe heat When passing through the tubes 19, the said chamber 20 is'provided with oppositely arrangedibalflesjll Whichterminate' short of each otherV and provide a contracted pas-'- ber23'. From the'ldifscharge chamber Q3,

Water is conductedback to the header 13 by j a*plurality off tubes 24, though uponritsr'eturn to the header 13, the Water is j means of Y discharged into the delivery compartment of the invention.

17 from whence it makes its Way through the port'25 to a Water jacket 26 which covers and 2/1 and termi# i ofV the device at l the lovver portion of the transferring header j both banks ofV tubes 19 nates on the oppositeside eXtensive With the Which is capable of` absorbing substantially all' offtheheat not absorbed by the banks of Copiesl of this patent may be obtained fior saevva 22o eninO in the dischar e cham-k headers and tubes, and

tubes 1f) and 24:, thereby;y forming. an eX- tremely efficient heater. It is thoughtI from the explanation of the structural features of the several forins of the invention that the many features and advantages of the same are readily apparent, and itvvvill of course be understood that kminor details of construction maybe changed Without :departing `from the spirit or sacrificing any of the advantages of the invention.

I claim: i f
